MARINE BICYCLE.

Specification of Letters Patent.

Application filed July 1, 1909.

T 0 all who m it may concern:

Be it known that we, CARL F. KRAUsn and RUnoLr C. KRAUsE, citizens of the United States, residing at WVestfield, in the county of Marquette, State of lVisconsin, have in vented certain new and useful Improvements in Marine Bicycles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to marine bicycles, and has for one of its objects to improve the construction and increase the efficiency and utility of devices of this character.

With this and other objects in view, the invention consists in certain novel features of construction as hereafter shown and de scribed and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention, Figure 1 is a side elevation of the improved device. Fi 2 is a transverse section on the line 2-2 of Fig. 1. Fig. 8 is a plan View ofthe improved device. Fig. 4 is a longitudinal section on the line 4-4 of Fig. 8. Fig. 5 is an end elevation viewed from the bow.

The improved device comprises two boats 10-11 spaced apart, the boat 10 being provided with a longitudinal elevated member 12, and the boat 11 provided with a similar longitudinal member 18. Extending across the members 12-18 near their ends are tie members 14-15, said tie members being recessed into the members 12-18. The members 12-18 and 1415 form a frame whereby the boats are firmly united, and maintained in their spaced relations, with their keellines in parallel relations. Bearing upon the members 14-15 is a supporting platform or deck formed in two sections 16-17, the confronting edges of the platform members being spaced apart midway between the two boats.

Bearing upon the deck portions 16-17 is a longitudinal housing, preferably formed of relatively heavy sheet metal or plate metal and comprising the body portion 18 and lateral flanges 19-20, the flanges being arranged to bear respectively upon the deck portions 16-17 and rigidly connected thereto by bolts, screws, or other suitable fastening devices 21-22.

Connected beneath the transverse members 1%15 is a longitudinal supporting member 28, the latter extending at the bow and stern portion of the deck members 16- 17 as shown. The member 28 is provided at the forward or bow end with a longitudinal slot 24 in which a chain wheel 25 is mounted for rotation upon a shaft 26, while a similar slot 27 is formed in the stern portion of the member 28 and in which a chain wheel 28 is mounted for rotation upon a shaft 29. An endless chain80 is mounted upon the chain wheels 25-28, the lower side of the chain being thus arranged to move close to the water line. Connected to the chain 80 at suitable intervals are paddles 81, as many of the paddles as required being employed. The paddles are arranged to move in the water when the chain is operated, as will be understood. The chain wheels 25 and 28, the chain 80, and its paddles 81 are so arranged that the upper side of the chain and its paddles pass through the housing 18, as shown.

Mounted for rotation in the member 28 rearwardly of the chain wheel 28 is a rudder post 82 having a rudder 88, and with a cable sheave 84 at the upper end of the rudder post. I

Mounted upon the deck members 16-17 is a supporting frame, preferably constructed from tubing similar to ordinary bicycle frames, and comprising a back-bone member 85, forwardly arranged oblique brace members 86-87 and rearwardly arranged oblique brace members 88-89. The

brace members 86-87 are coupled to the back-bone 85 by a coupling element 40, while the brace members 88-89 are coupled to the back-bone member by a coupling element 41. The lower terminals of the various brace members are seated in socket plates attached by bolts, screws or other fastening means to the deck members, and as these socket plates are precisely alike they are designated by the single character 42. By this means a rigid supporting frame is provided to which the operating mechanism is connected, the parts being constructed and united, as before stated, in the same manner as an ordinary bicycle frame.

Formed in the back bone member 85 near the forward end is a bearing 48 through which a vertical post member 44 is mounted for rotation, the post member stepped at its lower end at 45 upon the housing 18 and provided at its upper end with a turning wheel 46. Connected to the post 44 is a cable sheave LT. Mounted for rotation upon the deck member 16 are spaced guide sheaves 4%8-49, and similarly mounted for rotation upon the deck member 17 are similar guide sheaves 51. A cable 52 leads from the sheave 34 of the rudder post to the sheave H, and passing around the guide sheaves %8+l9, while a similar cable 53 is connected to the sheaves 34 and 4:7 and passes around the guide sheaves 505l. By this means it will be obvious that oscillatory motion imparted to the post A by the steering wheel 46 will control. the movement of the rudder Idler guide sheaves may be arranged to control the movement of the cables and cause them to run truly over the various sheaves, as will be obvious.

Formed in the back-bone member near its rear end is a socket 5G, and supported in this socket is apost member 57, the latter being preferably arranged at a forwardly extending angle. The post 57 is suitably supported from the brace members 3839 by diagonal braces 5859. The upper end or the post 57 is utilized to support a seat 60 of the usual form employed upon bicycles, and mounted for rotation in the lower end of the post 57 is a crank axle 61 having treadles 6362 at its ends, the crank axle and the treadles being of the usual form employed upon bicycles. A chain wheel 67 is connected to the crank axle 61,, and a smaller chain wheel (34. is connected to the shaft 29 alongside the chain wheel. A driving chain (35 is arranged to lead over the chain wheel 63-434. By this means a person occupying the seat 60 and operating the treadles, will thus impart motion through the chain 65 to the shaft- 29 and then to the chain 30 and its paddles 31. The steering wheel 46 will be located in the same position relative to the seat as in an ordinary bicycle. The housing 18 is cut away as represented at 66 to permit the chain 65 to operate, as represented in Fig. 1.

The improved device is simple in construction, can be inexpensively manufactured, is compact strong and durable, and

thus able to withstand the severe strains to 50 which it will be subjected when in use, or when operating upon rough Water hat is claimed is 1. In an apparatus of the class described,

two boats spaced apart, an upwardly di- 55 rected base member extending longitudinally of each boat, each base member being provided with spaced recesses, transverse members engaging in said recesses and secured to said base members, deck members 0 connected to said transverse member with their inner edges spaced apart, an upwardly arching housing connected to said deck members and extending over the space between the same, a supporting member 0011- 5 nected beneath said transverse members and extending at the ends forwardly and rearwardly ot' the deck members, chain wheels mounted for rotation upon said supporting members, an endless chain carrying a plu- 70 rality ot' paddles spaced apart and operating over said chain wheels, and chain operating means supported upon said deck members.

In an apparatus of the class described,

two boats spaced apart, deck members carried by said boats with their inner edges spaced apart, an upwardly arching housing connected to said deck members and extending over the space between the same, a supporting member connected beneath said deck members and extending at the ends forwardly and rearwardly 0f the deck memhers, chain wheels mounted for rotation upon said supporting member, an endless chain carrying a plurality of paddles spaced apart and operating over said chain wheels, and chain operating means supported upon said deck members.

In testimony whereof, we atiix our signa-
